Human actions can really change how nature works in several important ways:
Habitat Destruction: When people build cities or cut down forests, it can harm the environment. This means fewer places for animals and plants to live, which can lead to some species disappearing. For example, when forests are cleared for farming, many animals lose their homes.
Pollution: Pollution can change how some animals survive. Take the peppered moth, for example. In cities with a lot of soot, these moths became darker because the darker ones were harder for predators to see.
Climate Change: People are causing climate change, which is shifting the homes of many species. Animals like polar bears are having a tough time because their ice homes are melting.
Overhunting and Fishing: When people hunt or fish too much, it can change the traits of the animals left. For instance, if larger fish are often caught, the fish that are left might be smaller in future generations.
These actions can speed up or slow down how different species change over time, showing just how much our choices impact the natural world.
