The environment is the water, air and land where all the animals, plants and humans live. Dan The Gardener and his friends respect and help nature whenever they can.
Just like humans the environment needs to live a healthy lifestyle to live longer. Humans become unhealthy by eating too much or not enough, or because of not exercising enough.
The environment becomes unhealthy because of what humans have done. The problems include:
Dropping litter, this pollutes the land and looks horrible
Air pollution - large factories and motor vehicles (cars, motorbikes and buses etc.) pollute the air with toxic fumes.
Sewage - sewage that is dumped in the sea and rivers makes it unsafe for us to swim in some places. It also makes it hard for under water animals to live because the pollution destroys the oxygen in the water.
Deforestation - where too many trees are being cut down without replanting
Sustainable Forests are forests that have a continuous growth cycle of trees so as the trees are cut down there are more trees growing to replace them.
