Local usage. A lot is usually a smaller parcel of land - for example, a city lot, but a parcel is a larger amount, such as farm lands, acreage, or building sites for multiple dwellings or apartment blocks.

In some cases, a lot is developed land - that is, it will have access to sewer, water and electricity, but a parcel is undeveloped land.

Animal rights and environmentalism often have conflicting views. For instance, wind mills, which are an increasingly popular alternate energy source, often have to be placed in the migration route of birds to maximize power, killing thousands or millions of birds each year. Sometimes, though, they intersect. Cows produce a lot of methane, so to destroy the meat industry would be to reduce toxins on the earth. People who are conscious of gender justice are generally humanitarians, so those two things are tied together. I don't know that they tie in to the other two. Certainly, people who are involved in these things generally (I said generally, not always!) tend to be left-leaning, so they are more likely to learn about these other important issues.
