Genes are thought to contribute a certain amount to the cause of autism but it's not 100 per cent. It might be about 60 per cent genetic. So there are going to be environmental factors that mediate the impact of autism.

There are so many different environmental factors for just how safe it is for a kid to come out.

I do comparative studies of climate evolution, and the interactions between planetary atmosphere and surfaces and their radiation environment, and try to understand the environmental factors that can affect a planet's habitability and how they change over time.

We know that the environment and political information is important, and we expose and teach the women about some of the environmental factors that lead to their incarceration.

China is bearing the environmental cost for much of the world because China is the factory of the world.

It's worth knowing more about the complicated environmental and genetic factors that could explain why traumatic brain injuries lead to long-term disabilities in some people and not in others.

What causes autism? As far as we know in 2013, there is no single gene or single environmental factor that accounts for the more than 1 million Americans with ASDs.

Factory farming is one of the biggest contributors to the most serious environmental problems. The meat industry causes more greenhouse gas emissions than all the cars, trucks, planes and ships in the world.

A variety of factors contribute to the price of gasoline in the United States. These factors include worldwide supply, demand and competition for crude oil, taxes, regional differences in access to gasoline supplies and environmental regulations.

I think it makes people in the Pentagon kind of nervous to know that chemical agents and environmental factors could cause so much damage in terms of what may happen in the future.

What is basically just an IQ score has roots in education, socioeconomic status, genetics, and environmental factors. Looking at any one of these roots doesn't give you a full picture of the tree, but it does tell you that a tree is there.

We learned that kicking down doors to free children from carpet factories isn't enough to stop child labour - we had to tackle the underlying poverty in which their families lived, through education.

Education is a state-controlled manufactory of echoes.

While there are many obstacles that deter students from going to college, finances by no means should be the deciding factor.

The most influential of all educational factors is the conversation in a child's home.

Hollywood is the dream factory, and no one dreams about older women.

Throughout my life my greatest benefactors have been my dreams and my travels; very few men, living or dead, have helped me in my struggle.

The most important factors for a long life, I think, are partly in the genes; number two is lifestyle, which includes healthy diet and regular exercise. I walk, run and swim every day. However, I think too much exercise is also unhealthy because of over-stress; sometimes people who exercise too many hours per day die early.

We are also in the process of defining how best to work together with food and other companies to address diet and physical activity factors in order to prevent chronic diseases.

The benefits of a healthier diet are far-reaching because they also equate to fewer animals being bred into inhumane factory farm conditions and fewer greenhouse gas emissions.

Such lifestyle factors such as cigarette smoking, excessive alcohol consumption, little physical activity and low dietary calcium intake are risk factors for osteoporosis as well as for many other non-communicable diseases.

The primary factor is proportions.

The die is set and Malcolm will not escape for the foolish talk he spoke against his benefactor, such a man, is worthy of death, and it would have been so, were it not for Muhammad's confidence that God would give him the victory over the enemies.

Why do we take pleasure in gruesome death, neatly packaged as a puzzle to which we may find a satisfactory solution through clues - or if we are not clever enough, have it revealed by the all-powerful tale-teller at the end of the book? It is something to do with being reduced to, and comforted by, playing by the rules.
