Terminal extinction is happening frequently around the world, to precious and diverse animal species, which is a huge loss to all living things on the planet. The major factor in environmental degradation is humans. Communities are more susceptible to future land degradation as well as to socioeconomic and political forces due to the long-lasting effects of land degradation, such as soil erosion and contamination. (Source: Stanford Law School), A civil engineer is finding ways to model informal settlements in tropical regions, and using these models to help find universal solutions for extreme heat. While degradation means the decline in the quantity and quality of natural resources, pollution is the release of harmful substances into the air, water, and soil environment. This is because they carry out activities that directly damage the environment or indirectly damage it through the release of substances that cause environmental degradation. What Causes Extinction & How Can We Prevent Species Extinction? The intertwined relationships among the food system, climate change, and biodiversity loss are placing immense pressure on our planet.

Agriculture is also responsible for 90% of global deforestation and accounts for 70% of the planets freshwater use, devastating the species that inhabit those places by significantly altering their habitats. Habitat loss also greatly reduces genetic diversity, as fewers individuals remain to breed naturally and create genetic diversity. This means that environmental degradation will on a general note, mean a negative occurrence in the environment. According to the worlds leading climate scientists, around 75 percent of land environments have been severely altered by human actions, as well as about 66 percent of marine environments. Human Extinction from Natural Hazard Events There are two types of components in ecology and these are biotic and abiotic factors. Our current food system is hungry for land and again animal agriculture is responsible. Explanation: The introduction of non-native species is the Human-induced altering of species composition which is sometimes damaging to local communities and Why was the decision Roe v. Wade important for feminists? Millions of tons of greenhouse gases that are typically trapped in wood as carbon might be released into the atmosphere as a result of excessive forest cutting or thinning, which can disrupt the global climate. Activities such as restoration of green cover, cleaning up of landfills, protection of endangered species, rehabilitation of internally displaced people, reconstruction of damaged buildings and roads, and cleaning up of the large volumes of spills, are geared towards mitigating environmental degradation and remediating already degraded areas is quite expensive.
