According to articles I read, a conservative mode income used for housing should be 25% of after-tax income or take home pay.
Dave Ramsey said "Your mortgage payment should not be more than 25 percent of your take-home pay and you should get a 15-year or less, fixed-rate mortgage.."
The crisis of biodiversity will lead to a food crisis for humans because:
1.No varieties in certain foods like plants and animals that are healthy
2.The Less food there is,more animals go extinct which means humans will go extinct too.
and finally 3: Without certain types of species like the bee, humans have no chance of survival (since bees pollinate flowers,fruits,and plants which could be used for human consumption and medicine)
