Answer:
Global warming, less population in animals and insects, and pollution in sea life.
Explanation:
Global warming is one of the most aware cause of the Earth because animals are dying based on the climate's temperature
Less population in animals and insects are one of the risk factors. Think of bees - bees give us honey and nutrients. People are killing bees because they 'kill' us, they're considered 'pests', but they give us nutrients and especially, flower life. Without bees, we can't get the nutrients we need.
Pollution in sea life is one of the most concerning problems on Earth. Turtles are eating plastic bags, and unwanted objects into their system. Luckily, people are making clothing's, shoes, and other objects to reduce pollution, and help sea life increase so they won't become extinct in the future.
