ПОМОГИИИТЕЕЕЕЕ ПОЖАЛУЙСТА Пожалуйста ДАЮЮЮ 100 БАЛЛОООВВ Task: read the text and mark the sentences as T (true) or F (false)..
Eating right makes sense for your health, the health of your loved ones and the health of the
planet. Making sure we do the right thing when it comes to food shopping is “a piece of cake”!
So, try to .... Eat less meat. The UN says that livestock, animals raised for food, are responsible
for 18% of the planet's greenhouse gases. Hard to believe, but if humans stopped eating meat, it
would help the environment more than if we stopped all transportation activity on the planet!
That's right, just by giving up our burgers we would be doing more for the Earth than if we
stopped all the world's flying, driving and shipping of goods. .... Take advantage of foods grown
locally. This means you'll be eating fruits and vegetables that are fresher and wrapped in less
packaging. In addition, you can find out from the farmer exactly how they grow their produce
and what steps they take to protect the soil that they are grown in. And buy in season. Produce
will be tastier and less energy will have been wasted to get it to you. Quantities is smart shopping
for two reasons: little or no packaging and lower prices. Experts say that packaging, plastic,
paper, aluminium foil, makes up around 30% of all waste in our landfill sites. Reduce that
number by buying in bulk or buying products in 100% recyclable.
