I think you need to find the right school, environment for your student - and environmental science can run the gamut of different areas of interest.
I’d figure out - are they interested in water or weather or do they want to be in a large school with sports or a small school.
If you looked at - say - U of Oklahoma - the environmental science degree is in the college of engineering - and students can choose one of three tracks.
Clemson has a focus on Horticulture, Plant and Environmental Sciences or Turfgrass. If you choose the plant and Environmental Sciences, you can focus in one of these areas: agricultural biotechnology, agronomy, or soil and water science.
Colorado State has a focus on EcoSystem Sustainability but also Watershed Science as part of their program.
Pick a mid size like College of Charleston, they have an entire school and yet their major focuses on geosciences.
If you picked an LAC - like Macalester or Haverford - they have less offerings - Studies, not Science. Colgate too but they have Environmental Geology. Wesleyan says this about their major: The Earth and Environmental Sciences Department (E&ES) at Wesleyan University covers many aspects of the natural world, on Earth and on other planets. Course topics range from active volcanoes to climate change to eco-conservation. The E&ES major is designed to prepare students for graduate school, as well as provide a basis for a variety of careers in the private or public sectors. Courses in geology, environmental science/environmental chemistry, environmental science/ecology, and planetary geology lead to different areas of specialization and career options
I think the environments are vastly different and I don’t think it matters if you are at an R1 or any other large university.
This is a case by case - and one thing I’d note is grad school may be likely or salaries low no matter where you go:
At UNC, the average salary for a 24 grad as reported is $55.3K. At Purdue, $54K last year.
Lafayette is one LAC i found the major - don’t know how many were in but 100% show going to grad school.
To me, there will be more opportunity for academic diversity at a university (forget R1) than an LAC -but ultimately these are different choices in lifestyle - and I would thin that matters most.
My son went to a large R1 and did a minor in Geography - which hosts the Environmental Science Department and offers focuses in Natural Resources and Ecosystem Conservation.
While my daughter didn’t study this and didn’t go to an R1, I don’t think she’d have been deprived of any opportunities my son could have had.
And an LAC - I do think in many cases resources or offerings might be less but at the same time if it’s a small major, there may be more focus on the student.
I would find the right school and not worry about lists - and I would find a school that will cover your student’s specific academic interests because different schools focus on different sub areas.
Best of luck.
