Human activities really change how nutrients move through natural ecosystems. This is interesting to see, but it can also be a bit scary. Here are some main ways this happens:
Farming Practices: When farmers use fertilizers, they add extra nutrients, like nitrogen and phosphorus, to the soil. Sometimes, these nutrients wash away into rivers and lakes. This can cause a lot of algae to grow, which harms the plants and animals living in the water.
Cutting Down Trees: When we remove trees, it makes it harder for ecosystems to cycle nutrients. Trees and plants are really important because they help take in and recycle nutrients.
Pollution: Waste from factories and cities can release bad chemicals into the soil and water. This changes the way these environments work and can hurt the organisms that help with nutrient cycling.
Taking Too Much from Nature: If we catch or harvest too many plants and animals, it can hurt the groups that help keep nutrient cycles balanced.
All of these activities can create a chain reaction, making ecosystems weaker and less able to bounce back from changes!
