When you run a company, you want to hand it off in better shape than you found it. In the same way, just as we shouldn't leave our children or grandchildren with mountains of national debt and unsustainable entitlement programs, we shouldn't leave them with the economic and environmental costs of climate change.

I urge President Trump to maintain American participation in the Paris Agreement - for the sake of our international leadership, economic competitiveness, and children's environmental future.

I started traveling out of curiosity, but I have come to believe in travel's political importance, that encouraging a nation's citizenry to travel may be as important as encouraging school attendance, environmental conservation, or national thrift. You cannot understand the otherness of places you have not encountered.

If we're going to pass international trade agreements, as we should, they should have similar kind of rules, not as high a wage as obviously as a steelworker in the U.S. or in Lorain, Ohio, but certainly rules on the environment and worker safety. You go to Mexico, you don't see those kinds of worker protections or environmental safeguards.

I have spent many years working in education and media, from hosting documentaries to being a spokesperson for Discovery Education to revolutionizing youth environmental service through my non-profit, EarthEcho International.

In May 2007, congressional Democrats and the Bush administration agreed to a plan to include environmental and international labor standards in upcoming trade agreements.

As a nation, we owe a great deal to the National Audubon Society, one of our most distinguished and important environmental organizations, and all those who work to protect America's open land and waterways.

If China is helping its domestic industries charge an artificially low price for solar panels and other environmental goods, then China is violating international trade rules that it agreed to when it became a member of the World Trade Organization.

Without international participation, jobs and emissions will simply shift overseas to countries that require few, if any, environmental protections, harming the global environment as well as the U.S. economy.

We all recognize that in recent decades, many important achievements have helped create a cleaner, healthier environment, yet our national needs in environmental health are not being fully met.

This is absolutely bizarre that we continue to subsidize highways beyond the gasoline tax, airlines, and we don't subsidize, we don't want to subsidize a national rail system that has environmental impact.

But reducing harmful emissions, abating our dependence on foreign oil and developing alternative renewable energy sources have benefits that go beyond environmental health, they improve personal health, enhance national security and encourage our nation's economic viability.

The Environmental Control and Life Support System (ECLSS), which controls the living environment on shuttles and on the International Space Station, doesn't have the luxury of disposal: discharging trash into space has long been judged a bad idea.

In a world of serious threats to the U.K. and to global stability, where we see violence and conflict pulling people back into poverty, international terrorism, migration crises, children dying from preventable diseases and global environmental concerns on the rise, Britain's leadership on the world stage is more important than ever.

As the leader of an oil-producing nation, I know how hard it can be to prioritize environmental issues, but the short-term risk to our economic security is far outweighed by the potential risk to our national and regional security.

The Environmental Protection Agency's first-ever limits on carbon pollution from power plants will create clean- energy jobs, improve public health, bring greater reliability to our electric power grid, bolster our national security, demonstrate the United States' resolve to combat climate change and maybe even reduce our utility bills.

Hydrogen holds great promise to meet many of our future energy needs, and it addresses national security and our environmental concerns. Hydrogen is the simplest, most abundant element in the universe.

The high prices also highlight the fact that the U.S. is too heavily dependent on fossil fuels that we import from unstable parts of the world. To protect our national security, we must become more energy secure.

Global markets must be balanced by global values such as respect for human rights and international law, democracy, security and sustainable economic and environmental development.

I think the environment should be put in the category of our national security. Defense of our resources is just as important as defense abroad. Otherwise what is there to defend?

We need to save the education system. We need to remove education from the framework of the political parties that rule in the State of Israel. We need to increase the allocation of long-term national resources to education and never touch them - no matter what.

Instead of a national curriculum for education, what is really needed is an individual curriculum for every child.

Without education, we are weaker economically. Without economic power, we are weaker in terms of national security. No great military power has ever remained so without great economic power.

But baseball bounced back in the next decade to reclaim its place as the national pastime: new heroes, spirited competition, and booming prosperity gave birth to dreams of expansion, both within the major leagues and around the world.
