Yes, it would
benefit the ecosystem. Animal agriculature is harmful to the environment.
Think about this: You eat animals (or animal products), those animals have to eat more plants which had to be farmed, and that causes the clearing of more forests.
It's all basic thermodynamics.
When a chicken (for example) eats corn, most of the energy and protein is lost from the corn (and turns into CO2 and chicken poop), then if you eat the chicken, you get less energy and protein compared to eating the corn.
In another thread I recently calculated:
Feed conversion ratios for Chicken are around 2:1. A chicken is around 10% composed of "usable" protein.
That's 20kg of feed to 1 kg of protein.
Feed contains about 20% protein.
4 kg feed protein makes 1 kg chicken protein.
4 kg of plant protein, fed to chickens, only creates 1 kg of chicken protein. 3 kg are wasted. That's 75% waste.
If you eat chicken compared to a grain like corn (which the chickens are fed), you need four times more farmland.
Eating chicken, you have to clear four plots of forest, and turn into farm land. You destroy the environment.
If you eat vegan, you only need to clear one plot of forest to turn into farm, and you have three plots of natural environment left.

Well, see above.
We breed these animals. They do not exist "naturally". They come from factories where eggs are hatched. The cows are artificially inseminated.
If people stopped eating meat, we would stop breeding them. And then we could either allow many of those farms to return to natural environments like forests, OR we could use that extra corn to feed starving people, as the world's population keeps growing, OR we could even use the extra corn to make fuel, to replace oil -- this would help stop global warming.
We have lots of choices of what to do with all of the extra corn. But it certainly won't damage the environment to stop eating meat.
