Human activities are causing big changes in nature. These changes disrupt how animals and plants relate to one another. Here are some important ways this happens:

1. Habitat Destruction

   • Building cities and cutting down forests are leading to a loss of about 13 million hectares of forest every year. This loss means many animals and plants have fewer places to live. As a result, they compete more for food and shelter.

2. Pollution

   • Chemicals that get into the environment can harm ecosystems. For instance, when fertilizers wash off farms into rivers and lakes, they can cause algae to grow too quickly. This leads to less oxygen in the water, making it hard for fish and other creatures to survive because they have to fight harder for the remaining oxygen.

3. Invasive Species

   • When people introduce new species into an area, these invasive species can outcompete the native ones. It's believed that invasive species are responsible for about 40% of the animals and plants disappearing from the Earth. They hurt the natural relationships that native species have, making it tough for them to survive.

4. Climate Change

   • Changes in the climate, caused by human actions, are also affecting where different species live. As some animals and plants move to new areas, it messes up how they interact with each other and how they find food. By 2030, we could lose 1 million species because of climate change.

All of these issues together weaken the important balance of interactions in nature. This balance is vital for keeping the environment healthy and full of different kinds of life.
