Answer:
Mayor productividad de los cultivos.
Disminución de vertidos químicos en ríos y aguas subterráneas.
Mayor seguridad de los trabajadores.
Disminución del uso de agua, fertilizantes y pesticidas, lo que a su vez reduce los precios de los alimentos.
Explanation:
The correct answer is - the Americas.
The Americas from what is known and discovered till now are by far the latest continents that were settled by the people. Even though it is still not clear when exactly did this happened it is in the range between 19,000 and 12,000 years ago as the biggest given and lowest given number by scientists. It is understandable though that people found it hard to migrate in this part of the world since it was cut of by an ocean and the only way that they could migrate was through the Bering Land Bridge which in fact was an icy bridge between the continents and extremely inhospitable place. There is also the large carnivores in North America as a factor that delayed the migration, and of course the ongoing ice age which covered huge portions of North America with glaciers, ice and snow.
The difference between a hypothesis and theory is that the hypothesis is based on observations, but doesn't have a solid proof, while the theory is based on solid proof.
So in order for the scientist to make his hypothesis into theory about the connection of all the Earth's oceans, will need to provide a proof. This proof can be obtained by a sea traveling that will be well documented, and during the travel the scientist to manage to sail through all of the Earth's oceans without having any physical obstacle between any of them.
Cause they found and understood that america Latin was a new world
I don't know about it more
sorry,
Answer:
World human population is expected to reach upwards of 9 billion by 2050 and then level off over the next half-century. How can the transition to a stabilizing population also be a transition to sustainability? How can science and technology help to ensure that human needs are met while the planet's environment is nurtured and restored?
Our Common Journey examines these momentous questions to draw strategic connections between scientific research, technological development, and societies' efforts to achieve environmentally sustainable improvements in human well being. The book argues that societies should approach sustainable development not as a destination but as an ongoing, adaptive learning process. Speaking to the next two generations, it proposes a strategy for using scientific and technical knowledge to better inform future action in the areas of fertility reduction, urban systems, agricultural production, energy and materials use, ecosystem restoration and biodiversity conservation, and suggests an approach for building a new research agenda for sustainability science.
Our Common Journey documents large-scale historical currents of social and environmental change and reviews methods for "what if" analysis of possible future development pathways and their implications for sustainability. The book also identifies the greatest threats to sustainability—in areas such as human settlements, agriculture, industry, and energy—and explores the most promising opportunities for circumventing or mitigating these threats. It goes on to discuss what indicators of change, from children's birth-weights to atmosphere chemistry, will be most useful in monitoring a transition to sustainability.
