What are some of the most necessary, realistic and economically feasible changes that we need to make (in your lifetime) to sustain our planet and the people on it.

There are many changes that can be done in order to achieve a greener, more sustainable lifestyle that doesn't damage the environment. Some of the most accesible ones, in terms of practicality and easy economic access, for everyone are the following:

1) Swift to a plant-based diet. This is the most instant, most efficient change we can do to diminish environment-damage. The meat and dairy industries are responsible for over 80% of the gases responsible for the green house effect and other environment-damaging practices, such as: deforestation; ocean poisoning, and ozone cape-thinning. You may do the following changes in your diet to avoid contributing to the explotation of land, contamination of the oceans and thinning of the cape:

2) Adopt zero-waste habits. Meaning, try not to consume foods or goods that come in packages made of plastic or other unrecyclable materials, or materials like, as plastic, take over 200 years to desintegrate.

It is important not to buy these items if you do not need them right away: otherwise you are going to have to dispose of the ones you already have. Try to be consistent and implement at least one animal-product free day, or meal, and also take in more zero-waste habits.

you would times this by how many days there are in a year 365*400=$146000
