The future of the planet is being discussed at a meeting in Rio in Brazil today.
It marks 20 years since leaders agreed to cut down on global emissions and tackle global warming.
Many people think these promises haven't been kept and more needs to be done to reduce our impact on the world.
Hayley's been to the Isle of Mann to see how environmental changes are effecting them and if anything has changed.
The Isle of Mann has to cope with the same problems as the UK but because it's much smaller they can feel a lot closer to home.
