Rainwater harvesting is a technique which prevents rainwater to run off. But why is this necessary? And what are the results?
What is an ecosystem?
An ecosystem are all plants and animals together in a specific area together with their physical surrounding, such as the sunlight, the soil, the water and the air.
Ecosystems can be located on the main land, in the water or in the ocean and differ in size. Healthy ecosystems are always in balance, meaning the populations of animals and plants present in the ecosystem are remain more or less the same. The higher the number of different animals and plants within an ecosystem, the more stable the ecosystem is. This is also called the biodiversity of the ecosystem. Humans are largely depending on ecosystems. We take our food from nature, it helps to purify our water and the plants promote sequestration of carbon from the air.
