Sea level rise causes extreme contamination to water because it results in flooding. Realistically, in order to achieve targets 6.1 and 6.3, we will have to put a stop to climate change as it's causing majority of sea level rises.
If target 6.6 succeeds in restoring and protecting water in general, meaning decreasing plastic pollution as well, life underwater will be less threatened and certain species may no longer be in endangerment or risk of extinction. Additionally, there will also be a decrease in plastic found in water bodies and ecosystems.
Deforestation and degradation of land are usually when viruses jump from wildlife to humans. This is possible as degrading of land creates patches in the forest, attracting/gathering parasites in one place, then allowing diseases, illnesses such as tuberculosis, rabis to pass to humans. During the COVID-19 pandemic, immunization coverage dropped which caused the tuberculosis death rate to increase by 4.5%.
Due to how contaminated some places in the world are currently as well as how much progress we're making to decrease pollution, the deaths will skyrocket if stronger medication and /or vaccines aren't developed by 2030. This specific group at UNDESA and UNFCCC Secretariat are working to enhance, study, develop vaccines.

SDGs

Life Underwater

Coastal eutrophication is causing algal blooms and dead zones which are areas with limited oxygen, preventing life such as seals to survive there as it will result in suffocation. In addition, they are also causing crustacean walk-outs, meaning mass amounts of crustaceans are being washed up at shore.

Ocean warming is mainly caused by rising amounts of greenhouse gasses such as carbon dioxide. This disaster is generating sea level rise which is resulting in floods around the world. Ocean warming also has major negative impacts on the marine ecosystem, including acidification, an increase in toxic gasses which heavily pollutes the water. Target 14.3 was created in hopes to minimize acidification but as of 2023, the co2 levels are rising due to increasing commissions and will continue to rise until the ocean is 40% more acidic than pre-industrial times. Fun Fact! Over the course of 3 years, ocean acidifications were so extreme that the reporting stations for it tripled! (2021 - 178, 2022 - 308, 2023 - 539)

Plastic pollution by far causes the most issues underwater and to life there as well. By 2021, there were roughly 17 million metric tons of plastic pollution in the depths of the oceans and it is estimated that by 2040, there will be 3-4x more. Many citizens have recognized this problem, its impacts to our world, in attempts to resolve this issue, people are starting to arrange beach clean-ups.

Overfishing not only affects the type of fish that is captured but also its natural predator as it can now run out on its source of food and potentially starve to death. The governments have taken action and protected certain species by making them illegal to fish for but this has not helped much considering the rate of overfishing has increased 1.7% since 2017. Fun fact! More than a third of global fish stocks are overfished!

Clean Water And Sanitation

As of 2022, only 22 countries have made substantial progress regarding water and water-resource management with roughly 2.2 billion people around the world lacking safely managed drinking water and more than 3.5 billion people lacking basic sanitation. In order to reach the water and sanitation goal, 5x better sanitation is needed as well as 6x more safe drinking water available.

Targets 6.1 and 6.3 aim to change our water quality and amount of healthy, bacteria-free drinking water. As of 2023, there has been a good amount of progress made on target 6.1 but more than 2.2 billion individuals around the world still lack access to healthy drinking water. As of target 6.3, minimal progress was made with major impacts considering in 2022, 58% of wastewater generated by households was safely treated.

As of 2022, roughly 2.4 billion people live in water-stressed countries. Qatar, Israel and Lebanon are by far the most water-stressed countries mainly due to agriculture as well as agricultural uses and issues such as domestic production and groundwater resources.

In 2020, target 6.6 attempted to restore and protect water as well as related ecosystems. These may include mountains, forests, wetlands, rivers, lakes and aquifers. In 2023, it was proven that many surface water bodies like rivers experienced unusual and rapid fluctuations during the last 5 years. Common fluctuations for river-basins may include faster draining and temperature fluctuations.

Climate Change

Over the years, climate change has resulted in sea leveling practically doubling which can result in many difficulties including 15x higher mortality rates from disasters and flooding. If action is not taken, our world will exceed 1.5 degrees celsius by 2035. If we still refuse to do anything by then, our world will face 2.5 degree celsius warming by 2100.

Climate change is not only affecting the environment but also impacting the world's economics. If action is not taken, global warming finance flows for developing countries will eventually reach an average of 6 trillion dollars annually in 2030.

Target 13.3 helped spread awareness regarding climate change and how it affects the living. An analysis made for this target determined that 47% of people don't mention climate change or anything related to it. This number cannot continue to rise if we want to establish this goal by 2030. Target 13.3 is now aiming to raise awareness on institutional capacities on climate change mitigation, adaptation, impact reduction and early warning. In 2022, 95% of all teachers are familiar with this subject but only roughly 31% are able to explain this topic with effectiveness as well as clarity.

In mid 2023, UNDESA and UNFCCC Secretariat assembled “The expert group of climate and SDG energy”. This group was given the task to develop the first global report on climate and SDG energies in an attempt to expand on insights regarding the topic as well as offering a broader overview of what we have to achieve by 2030. As of now, it seems they are working on enhancing synergistic actions which are essentially mixed chemicals, drugs that provide a stronger effect/reaction.

Life On Land

It has been proven that as of 2023, we have been facing the deadliest animal endangerment and extinction occurrence since dinosaurs went extinct, possibly due to poaching, trafficking as well as diseases. The objective of Target 15.7 is to put an end to this issue by taking immediate action on making it illegal to poach protected species of flora and fauna as well as mention anything illegally related to animal endangerment.

Target 15.4 is progressing towards making sure the conservation of mountain ecosystems enhance their capacity to provide benefits that are necessities for the sustainable development of countries, ecosystems and more.

About 100 million hectares of healthy land was degraded yearly from 2014-2019. Forest losses, land degradation threaten people and the planet by causing inconveniences such as soil erosion.

Targets 15.1 and 15.2 aimed to ensure, manage and specifically restore, the conservation of terrestrial and inland freshwater ecosystems along with their services including forests, wetlands and mountains. As of 2023, the world’s forest areas have decreased by roughly 100 million hectares from 31.9% to 31.2%.

Good Health And Well-being

Over the span of 2 years (2019-2021), the amount of minors missing out on important routine immunizations increased by 24%. Target 3.b supports and occasionally funds the development as well as research of medication and vaccines. In 2023, it was proven that there is not much progress being made regarding the percentage of children that received three doses of vaccine for DTP3 (diphtheria, tetanus and pertussis). In fact, it has declined causing the largest sustained decline in childhood vaccinations in around 30 years.

Throughout the years 2010-2023, successful HIV treatment has cut AIDS related deaths by more than half with the help of all targets including support on financial issues regarding treatments (health coverage), funding of production and development of treatments, as well as universal access to healthcare and healthcare services.

Target 3.9 thrives to reduce the number of deaths, diseases and illnesses from hazardous chemicals and air pollution, including water and soil contamination. As of 2022 and 2023, there are not many confirmed updates regarding the progress made other than that annually, there are around 8.9-9.2 million deaths due to these concerns. Considering the state of our world’s environment, this number is predicted to rise to roughly 15 million by 2030 if no action is taken.

It was proven in April of 2022 that ever since the COVID-19 pandemic started in early 2020, it has infected more than 500 million people and killed more than 6.2 million universally. The coronavirus caused extreme interference with necessity including essential health services, shortened life expectancy and many more. Additionally, immunization coverage dropped for the first time in 10 years and deaths from tuberculosis and malaria increased by 4.5%.
