The Royal Society for the Protection of Birds (RSPB) have warned that cuts to farmers' subsidies would be harmful for UK wildlife
For the past 25 years, farmers across Europe have been given money by the European Union to look after animals on their land, whether they're in the fields or the hedgerows.
They say the cash has helped them to protect some of the UK's most endangered species, which might not be able to survive without the extra help.
All the countries that are part of the EU, like Britain, France and Germany give money and the funds are shared out to projects across Europe.
But with many countries experiencing big money problems at the moment, the EU is under pressure to cut how much it spends.
