Human population growth is a problem in that most humans consume more than they need. The Earth's resources are now strained to sustain the needs and wants of the human population, which continues to escalate.

Most of the plants grown to be fed to farm animals are heavily saturated with pesticides and herbicides and have been genetically modified, all of which contributes to the pollution and destruction of our environment, which harms us all.

It's important to understand that calcium isn't just about what you eat; it's also about what you keep. Acidic animal products mine minerals like potassium, magnesium and calcium from our bodies. In fact, the countries that consume the most dairy have the highest rates of hip fracture and osteoporosis.

The best we can do is strive to minimize the amount of harm we cause by living. We need to eat in order to live, and there is no moral or ethical code that dictates that we should refrain from eating and allow ourselves to die for some higher purpose.

As humans, we do get to choose what we eat, and when we choose to eat a plant, we are eating (i.e., harming) just that plant, plus indirectly whatever nutrients that plant consumed over its lifetime (and we are also harming whatever beings may have been living on that plant or who were injured or killed in the harvesting process). But when we eat an animal, we are eating not just that animal, but also indirectly all of the plants and other beings that that animal ate over its lifetime - those plants became the flesh that we eat.

Some well-to-do parents may say, "I have a right to have as many children as I want because I can take care of them." That may be so, but can the Earth take care of them?

Remember that everyone you see and every situation you find yourself in has come from inside of you; you have created your reality by how you have treated others in your past.
